The P117B fault code is related to the Engine Control Module (ECM) monitoring the air fuel ratio in any cylinder. When the ECM detects a lean or rich air fuel ratio state in any cylinder for a specific duration, it sets the P117B code.

This code specifically refers to the Cylinder AF Imbalance Monitoring in Bank 2. In simpler terms, this fault code indicates that there is an imbalance in the air fuel mixture in one or more cylinders on the second bank of the engine. This imbalance can lead to issues with the engine’s performance and fuel efficiency.

It is important to address this issue promptly to prevent further damage and ensure optimal engine operation. A professional diagnostic and repair service is recommended to accurately identify and fix the underlying cause of the imbalance.
